P39.02: Fetal echocardiography in ovarian cysts

The aim of the study was to estimate the outcome of fetuses with ovarian cysts in relation to fetal echocardiography. Computerized records of fetuses that had undergone echocardiographic examination between 1995 and 2006 at our department were searched for cases with ovarian cysts. There were 38 fetuses with suspicion of ovarian cyst. From this group 27 cases were confirmed postnatally. 16 fetuses with normal heart anatomy (NHA) were qualified to the study group. Fetuses with congenital heart defects (five), incomplete follow-up (four), major extracardiac malformation (two) were excluded from study. Study group was divided in three subgroups: (1) spontaneous regression without surgery—eight fetuses; (2) spontaneous regression after prenatal intervention -three fetuses; (3) postnatal surgery -five fetuses. All newborns survived with good outcome. Retrospective evaluation of cardiac functional anomalies was analyzed in subgroups. In nine out of 16 (56%) fetuses there was a normal heart study (NHS). Seven out of 16 fetuses (44%) presented functional anomalies: myocardial hypertrophy (five), pericardial effusion (one), tricuspid valve insufficiency with fetal heart disproportion (one). In subgroup 1, NHS was in six fetuses and two fetuses presented functional anomalies. In subgroup 2, NHS was in one fetus and two fetuses presented functional anomalies. In subgroup 3, two fetuses had NHS and three presented functional anomalies. Fetal echocardiography in fetuses with ovarian cyst with normal heart study without functional abnormalities was frequently related with spontaneous regression of fetal ovarian cyst.
